China certifies first domestic 1,100kW turboshaft helicopter engine, reducing reliance on Western tech and boosting Made in China 2025 aerospace goals.
China’s aviation sector has taken a decisive step forward with the approval of the AES100, the country’s first domestically developed 1,100-kilowatt turboshaft helicopter engine. This development marks a critical milestone in Beijing’s broader effort to achieve technological self-sufficiency in aerospace, particularly amid escalating export restrictions from the United States. The AES100, developed by the state-owned Aero Engine Corporation of China (AECC), has now received a type certificate from the Civil Aviation Administration of China (CAAC), signaling readiness for mass manufacturing and integration into operational platforms.
For decades, China has relied heavily on foreign suppliers for high-performance aircraft engines, particularly from Western countries. However, ongoing geopolitical tensions have intensified the urgency of establishing an independent aerospace supply chain. The AES100 is not just a technical achievement; it is a strategic move aligning with national priorities like the “Made in China 2025” initiative, which emphasizes domestic innovation in high-tech industries, including aerospace propulsion systems.
While the AES100 is primarily intended for helicopter applications, its successful development sends a broader message: China is narrowing the gap with global aerospace leaders and asserting its ambition to become a dominant player in both military and civilian aviation markets. The implications of this development extend beyond engineering into areas of national security, economic competitiveness, and global market dynamics.
The AES100 represents a new generation of turboshaft engines designed to power medium-lift helicopters used in both civilian and military contexts. According to AECC, the engine meets or exceeds performance standards required for advanced rotorcraft, including efficiency, reliability, and operational flexibility. The 1,100-kilowatt output positions it competitively against international counterparts, enabling China to reduce dependency on imported engines from manufacturers such as Safran Helicopter Engines (France) or General Electric (US).
One of the key breakthroughs in the AES100’s development was the integration of advanced materials and digital control systems. These technologies improve thermal efficiency and reduce maintenance cycles, making the engine suitable for varied mission profiles, including search and rescue, transport, and reconnaissance. The engine’s modular design also facilitates easier upgrades and maintenance, aligning with global trends toward flexible, scalable propulsion systems.
Li Gaiqi, chief designer of the AES100, emphasized that the type certificate reflects “China’s ability to independently develop and manufacture advanced civil turboshaft engines.” This statement underscores not only the technical achievement but also the symbolic value of the AES100 as a proof of concept for China’s broader aerospace ambitions.
“The successful development of a new helicopter engine is a crucial step toward China’s goal of technological self-sufficiency in aviation.”, Dr. Li Wei, Beihang University
The timing of the AES100’s approval is notable, coming just days after the United States announced a new round of export restrictions targeting jet engine-related technologies. These measures have increasingly limited China’s access to critical aerospace components, effectively accelerating Beijing’s drive for indigenous innovation. By developing the AES100 domestically, China mitigates the risks associated with supply chain disruptions and geopolitical leverage over key technologies.
Economically, the AES100 positions China to capture a larger share of the global helicopter market, valued at approximately $20 billion annually. With a domestically produced engine, Chinese manufacturers can offer more competitive pricing, reduce lead times, and ensure better integration with locally developed airframes. This could make Chinese helicopters more attractive to emerging markets in Asia, Africa, and Latin America, where cost and availability are significant purchasing factors. Furthermore, the AES100 supports the broader goals of the “Made in China 2025” initiative, which targets self-reliance in high-tech sectors. The government has reportedly invested over $5 billion in civil aviation R&D in recent years, and the AES100 represents a tangible return on that investment. It also enhances China’s ability to project power and respond to emergencies domestically and abroad, reinforcing its strategic autonomy.
Despite the progress represented by the AES100, China still faces significant challenges in achieving parity with global engine manufacturers. Turboshaft engines require high levels of precision engineering, rigorous testing, and long-term durability under diverse environmental conditions. Matching the performance, fuel efficiency, and certification standards of established players like Rolls-Royce or Pratt & Whitney remains a long-term objective.
Certification, in particular, is a critical area. While the AES100 has received a domestic type certificate, international certification is essential for export opportunities and global acceptance. This process involves extensive testing and compliance with standards set by regulatory bodies such as the FAA (Federal Aviation Administration) and EASA (European Union Aviation Safety Agency), which can take years to complete.
Additionally, the broader ecosystem of engine manufacturing,including supply chains for high-temperature alloys, precision components, and advanced coatings,is still developing in China. Continued investment in materials science, manufacturing technology, and workforce training will be necessary to sustain momentum and close the remaining gaps.
The AES100’s development is emblematic of a broader global trend: the pursuit of strategic autonomy in defense and aerospace technologies. As geopolitical tensions rise, particularly between the US and China, countries are increasingly seeking to insulate their critical industries from external disruptions. In this context, China’s progress in helicopter engine development may prompt similar moves by other nations to localize production and reduce reliance on foreign suppliers.
US export controls have had a paradoxical effect. While intended to limit China’s military and technological advancement, they have also galvanized domestic innovation. According to aviation analyst Mark Thompson, “US export controls have inadvertently accelerated China’s domestic innovation. While China still lags behind in some advanced engine technologies, these breakthroughs indicate a narrowing gap.”
From a market perspective, the emergence of a capable Chinese engine manufacturer introduces new competition for established firms. If China can achieve cost-effective production and secure international certifications, it could disrupt current market dynamics, particularly in price-sensitive regions. However, reputational factors, service networks, and long-term reliability will continue to influence purchasing decisions globally.
The AES100 helicopter engine marks a significant achievement for China’s aviation industry. Beyond its technical specifications, the engine represents a strategic pivot toward self-reliance, driven by necessity and supported by sustained government investment. It showcases China’s growing capabilities in aerospace engineering and signals its intent to become a formidable player in both civilian and military aviation sectors. Looking ahead, the AES100 is likely to be the first in a series of domestically produced engines aimed at reducing reliance on foreign technologies. While challenges remain in areas such as certification, durability, and global competitiveness, the trajectory is clear. China is investing in its future as an aerospace power, and the AES100 is a milestone on that journey.

Joby Aviation and Metropolis Develop 25 US Vertiports for eVTOL Launch
Joby Aviation partners with Metropolis Technologies to retrofit parking garages into 25 vertiports across US cities, supporting a 2026 eVTOL commercial launch.
This article is based on an official press release from Joby Aviation.
Joby Aviation has announced a significant infrastructure partnership with Metropolis Technologies to develop a network of 25 vertiports across the United States. The collaboration aims to repurpose existing parking infrastructure into “mobility hubs” to support the commercial launch of electric vertical takeoff and landing (eVTOL) aircraft.
According to the company’s announcement, the partnership will leverage Metropolis’s extensive portfolio of parking facilities to create takeoff and landing sites in key metropolitan areas. By retrofitting existing structures rather than building new terminals from the ground up, Joby intends to accelerate the deployment of its air taxi service, which is currently targeting a commercial launch in 2026.
The initiative addresses one of the most critical challenges in the Urban Air Mobility (UAM) sector: the “last mile” connection. The integration of ground and air travel is designed to offer passengers a seamless transition from their vehicles to Joby’s aircraft, utilizing advanced artificial intelligence to streamline the process.
The core strategy of this partnership involves identifying and upgrading sites within Metropolis’s network, which expanded significantly following its recent acquisition of SP+. With access to over 4,200 parking facilities, the companies plan to select prime locations in high-density urban centers such as Los Angeles, San Francisco, and New York City.
Joby Aviation stated that this retrofit approach offers a distinct advantage over constructing standalone vertiports. By utilizing the top decks of existing parking garages, the partners can reduce upfront construction costs and navigate zoning requirements more efficiently. These sites will be designed to meet the Federal Aviation Administration’s (FAA) Engineering Brief 105A, which outlines the specific design standards for vertiport geometry, marking, and load-bearing capacity.
“For air taxis to deliver on their promise of seamless urban travel, they must connect directly with the existing ground transportation ecosystem. By leveraging existing parking infrastructure… we can maximize the value of those sites without needing to build infrastructure from scratch.”
, JoeBen Bevirt, Founder and CEO of Joby Aviation
Beyond physical infrastructure, the partnership emphasizes the integration of Metropolis’s proprietary technology. The company utilizes AI-powered computer vision to manage facility access and payments. In the context of air travel, this technology aims to facilitate a “drive-in, fly-out” experience. According to the release, cameras will recognize a passenger’s vehicle upon entry, automatically processing parking fees and initiating the check-in process for their flight. This system is intended to eliminate the need for physical tickets, gates, or kiosks, aligning with the industry’s push for a frictionless passenger experience.
“The real world is the next frontier for AI… We are taking the data and recognition capabilities we’ve built in our network and extending it to air travel, creating the seamless, personalized, and magical experience that is the foundation of the Recognition Economy.”
, Alex Israel, CEO of Metropolis Technologies
While the construction of full vertiports is a longer-term project targeting 2026, the partnership includes immediate operational steps. Metropolis subsidiary Bags Inc. will begin providing VIP baggage handling services for Blade Urban Air Mobility, a partner of Joby Aviation, in New York City. This service will support flights between Manhattan and major airports such as JFK and Newark.
Los Angeles has been identified as a primary market for the initial vertiport rollout. The companies are currently evaluating downtown parking structures that can be adapted to support high-frequency air taxi operations. This focus on Los Angeles aligns with Joby’s broader strategy to establish a foothold in regions with high traffic congestion, where the time-saving value of eVTOL aircraft is most apparent.
We observe that this partnership represents a divergent strategy in the race for UAM infrastructure. While competitors like Archer Aviation have partnered with Atlantic Aviation to electrify existing private aviation terminals (FBOs), Joby is betting on bringing aircraft closer to the consumer’s daily commute via parking garages.
The “retrofit” model proposed by Joby and Metropolis may offer scalability advantages. Parking garages are ubiquitous in city centers, whereas private air terminals are typically located on the periphery at airports. If successful, this approach could allow Joby to penetrate dense urban cores more deeply than competitors relying solely on airport-based infrastructure.
However, we note that retrofitting parking decks presents its own engineering challenges, particularly regarding the structural reinforcement required to handle the weight and dynamic loads of landing aircraft, as well as the installation of high-voltage charging infrastructure in older buildings.

Vertical Aerospace Targets Full VX4 Transition Flight in Early 2026
Vertical Aerospace advances VX4 flight tests with 10 piloted flights completed; full transition now targeted for early 2026 amid regulatory updates.
This article is based on an official press release from Vertical Aerospace and includes analysis based on publicly available financial filings.
On December 19, 2025, Vertical Aerospace released a significant operational update regarding the flight testing of its full-scale VX4 prototype. According to the company, the engineering team has successfully completed 10 piloted test flights since receiving a “Permit to Fly” from the UK Civil Aviation Authority (CAA) in November. While the company reports expanding the majority of the flight envelope, the critical milestone of full piloted transition, switching completely from vertical hover to wing-borne cruise, has not yet been achieved.
The Bristol-based eVTOL (electric vertical take-off and landing) manufacturer stated that weather constraints and limited testing windows have pushed the target for full transition into early 2026. This update comes shortly after the company unveiled “Valo,” its production-intent aircraft, earlier this month.
Since resuming flight activities on November 13, 2025, Vertical Aerospace reports that the VX4 prototype has undergone rigorous testing to validate its handling and safety systems. The press release highlights that the aircraft has successfully performed acceleration and deceleration maneuvers and tested various tilt positions for its rotors.
According to Vertical Aerospace, the Test-Flights campaign has achieved several specific technical milestones:
The testing program has successfully validated the in-flight deployment and stowing of rear propellers, propeller spin-up during wing-borne flight, and “prop-hold” functionality.
The company notes that the “majority of the transition envelope” has now been expanded, leaving only the final 10% of the tilt transition untested. The completion of this final phase is required to demonstrate the aircraft’s ability to fly purely on wing lift, a defining characteristic of viable eVTOL technology.
Alongside the flight test updates, Vertical Aerospace announced a regulatory achievement involving the UK Civil Aviation Authority (CAA). The Regulations has granted the company new privileges allowing it to approve its own “Flight Conditions” and issue Permits to Fly for specific scenarios.
In the press release, the company framed this development as a signal of regulatory confidence in their design and engineering processes. This authorization is expected to streamline future testing phases by reducing the administrative lead time required for certain flight approvals. It is important for industry observers to distinguish between the aircraft currently undergoing testing and the product Vertical Aerospace intends to bring to market. The operational update refers specifically to the VX4 prototype, which serves as a testbed for data gathering. However, the commercial future of the company rests on “Valo,” the production model unveiled around December 10, 2025.
While the VX4 validates the core physics and control laws, Valo features a redesigned airframe, updated wing architecture, and an under-floor battery system. The delay in the VX4’s full transition means that critical aerodynamic data needed to finalize Valo’s Certification profile, targeted for 2028, will not be fully available until the prototype completes its envelope expansion in 2026.
The delay of the full transition flight places Vertical Aerospace behind its primary United States competitors in terms of technical milestones. Competitors such as Joby Aviation and Archer Aviation successfully completed full piloted transition flights earlier in 2025. Furthermore, the European market saw a significant contraction earlier this year with the reported insolvency of Lilium in February 2025, highlighting the capital-intensive nature of the sector.
Financial-Results sustainability remains a key focus for Vertical Aerospace. According to the company’s Q3 2025 Business & Strategy Update, Vertical reported a cash position of approximately $117 million. Based on current burn rates, the company projects this capital will fund operations until mid-2026.
With certification slated for 2028, this creates a “funding gap” that the company will need to address. The shift of the transition milestone to 2026 may influence investor sentiment, as the market often looks to technical achievements as validation for further capital injection.
What is the difference between the VX4 and Valo? When will Vertical Aerospace achieve full transition? What is the company’s current financial runway?

Eve Air Mobility Completes First Flight of Full-Scale eVTOL Prototype
Eve Air Mobility conducted a successful first flight of its full-scale eVTOL prototype in Brazil, validating key systems ahead of 2027 certification.
This article is based on an official press release from Eve Air Mobility.
On December 19, 2025, Eve Air Mobility achieved a critical milestone in the development of its electric vertical take-off and landing (eVTOL) aircraft. The company, a subsidiary of Brazilian aerospace giant Embraer, successfully conducted the first flight of its full-scale prototype at the Embraer test facility in Gavião Peixoto, São Paulo, Brazil.
This uncrewed hover flight validates the fundamental architecture of the aircraft, which utilizes a “Lift + Cruise” configuration distinct from the tilt-rotor designs favored by some competitors. According to the company’s official statement, the test confirmed the functionality of the electric propulsion system and the 5th-generation fly-by-wire controls, performing exactly as computer models had predicted.
While Eve Air Mobility is entering the flight-test phase later than some of its primary rivals, the successful deployment of a full-scale prototype signals the company’s transition from design to execution. With a target Entry into Service (EIS) set for 2027, Eve is leveraging Embraer’s industrial backing to accelerate its Certification program.
The test conducted in Gavião Peixoto was a dedicated hover flight. This specific profile is designed to test the vertical lift capabilities of the aircraft before attempting forward wing-borne flight. The prototype utilized eight dedicated vertical lift rotors to maintain a stable hover, allowing engineers to assess aerodynamic performance and control laws in real-world conditions.
Johann Bordais, CEO of Eve Air Mobility, emphasized the significance of the event in a statement released by the company:
“Today, Eve flew… This flight validates our plan, which has been executed with precision to deliver the best solution for the market.”
Following this successful hover test, the company plans to expand the flight envelope throughout 2026. This will involve transitioning from vertical lift to forward flight, powered by the rear pusher propeller, and testing the aircraft’s fixed wing for cruise efficiency.
The prototype flown represents the configuration intended for commercial certification. Unlike “tilt-rotor” designs that rotate propellers to switch between lift and cruise modes, Eve has opted for a separated “Lift + Cruise” architecture. This design choice prioritizes mechanical simplicity and potentially lower maintenance costs. According to technical specifications released by Eve Air Mobility, the aircraft features:
At AirPro News, we observe that Eve’s successful first flight places it in a unique position within the “race to market.” While competitors like Joby Aviation and Archer Aviation have already logged significant flight hours with full-scale prototypes, including transition flights, Eve’s strategy appears to be one of deliberate, industrial-scale preparation over speed.
The “Lift + Cruise” design philosophy suggests a focus on reliability and operating economics. By avoiding the complex tilting mechanisms found in competitor aircraft, Eve may offer operators a vehicle with fewer moving parts and lower direct maintenance costs. Furthermore, Eve’s relationship with Embraer provides immediate access to a global service and support network, a logistical hurdle that independent Startups must build from scratch.
Despite being arguably the “tortoise” in terms of flight testing timelines, Eve holds the industry’s largest backlog of Letters of Intent (LoI), totaling nearly 3,000 aircraft. This massive order book indicates strong market confidence in Embraer’s ability to deliver a certifiable product.
Looking ahead, Eve Air Mobility has outlined a rigorous schedule for the next two years. The company intends to build five additional conforming prototypes in 2026 to accelerate data collection. These aircraft will be used to accumulate the hundreds of flight hours required for certification authorities.
Luiz Valentini, CTO of Eve, noted the disciplined approach to the upcoming testing phase:
“The prototype behaved as predicted by our models… We will expand the envelope and progress toward transition to wingborne flight in a disciplined manner.”
The company is targeting Type Certification from Brazil’s ANAC in 2027, with concurrent validation sought from the FAA (USA) and EASA (Europe). Commercial deliveries are scheduled to begin immediately following certification.
